I have used gi's from The cheap Cotton blends to Mitsuboshi. I find PINE TREE gi's are a nice gi to use.THe cut isn't the best in the bus but @ less than 100USD for a 14oz one i recommend it. I have also heard that KI is good. FYI IMO it's alot better to train with a heavyier gi during dojo kumite etc.It gets u accustomted to the weight,so when u go into kumite and wear a lgith one,you are having a ball. ALso a heavy gi is excellent for kata competition as it gives the extra snap and heck it looks alot better The Tiger claw are also really good Gi's. Affordable and not a waste of money . Try the pine tree though. Different "bolts" of fabric are used sometimes and taht leades to a difference in "hardness" of the material.eg; i bought 2 and one is softer(not lighter) than the other. A Gi shouldn't be stiff and should allow free movement.
